It will come right down to the wire this afternoon for Las Vegas hero Amy Purdy as to whether doctors will let her perform on Week 8 of ABC’s “Dancing With the Stars” this evening.

As Vegas DeLuxe reported last week, Amy was taken to a hospital and has been undergoing treatment all week for back-muscle spasms and a pulled rib after she complained last Monday about pain in her shoulder.

Amy is the extraordinary Paralympian who lost her legs below the knees from a bacterial infection on her 19th birthday. She has been dancing on two prosthetic legs with pro partner Derek Hough, also formerly from Las Vegas.

Until the injury, the duo was considered front-runners with high-scoring votes from the judges. Derek has already won five times as a pro, the most of any dancer on the longtime hit ABC series.

Amy says she wants to dance. She has had limited rehearsals between medical treatments but admits difficulty with muscle spasms pulling on her ribs.

“This was a tough week. I’m hoping the healing and positive thoughts will pay off and I’ll be back. I’m grateful to be feeling better,” she said.

She credits chiropractors, ice heat, turmeric tea and anti-inflammatories to help keep the swelling down.

“Fingers crossed it will all pay off and I will be back,” she added.

Her remaining competitors believe that she will work through whatever pain she is in to take part in the 3 p.m. taped dress rehearsal, but doctors will then have the last word for the live 5 p.m. West Coast satellite transmission for the primetime East Coast broadcast.
